& WARNING
To reduce the risk of injury when an airbag inflates , always wear
safety belts properly.
• If you are unrestrained , leaning forward, sitting sideways or out
of position in any way, your risk of injury is much higher.
• You will also receive serious injur ies and could even be killed if
you are up against the airbag or too close to it when it inflates ·
even with an Advanced Airbag~
page 146 .
& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System .
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front airbag when a rearward -facing child
restraint has been installed on the front passenger seat , nobody
can absolutely guarantee that deployment is impossible in all
conceivable situations that may happen during the useful life of
your vehicle.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, door, or roof .
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on ,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer .
& WARNING
If, in exceptional circumstances , you must install a forward -facing
child restraint on the front passenger's seat :
• Always make sure the forward -facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag .
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range , as far away from the
airbag as poss ible , before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position. ..,.

Repair, care and disposal of the airbags
Parts of the airbag system are installed at many different places on
your Audi. Ins tal li n g, r em ovin g, s erv ic ing o r re pairi ng a part in an
area of the veh icle can damage a part of an a irbag system and
prev ent th at system from working pr oper ly in a c ollisio n.
There are some important things you have to know to make sure
that the effect ive ness of the system will not be impai red and that
discarded co mpone nts do not cause inju ry or po llute t he env iro n­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
r isk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover , obstruct , or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way.
• Never attach any objects such as cup holders or telephone
mountings to the surfaces covering the airbag units.
• For cle aning the horn pad or instrument panel , use only a soft ,
dry cloth or one moi stened with plain water. Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust , or change any parts of the airbag system.
• All work on the steering wheel , instrument panel, front seats or
electrical system (including the installation of audio equipment ,
cellular telephones and CB radios, etc .} must be performed by a
qualified technician who has the training and spec ial equipment
ne cessary .
• For any work on the airbag system , we strongly recommend
that you see your authorized Audi dealer or qualified workshop .
• Never modify the front bumper or parts of the vehicle body.
& WARNING (continued)
• Always make sure that the side airbag can inflate without inter­
ference :
- Never install seat covers or replacement upholstery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use addit ional seat cushions that cover the areas
where the side airbags inflate.
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi ­
ately by an authorized Audi dealer .
• The airbag system can be activated only once . After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary.
• The airbag sy stem can be deployed only once . After an airbag
has been deployed , it must be replaced with new replacement
parts designed and approved especially for your Audi model
version. Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure th at any airbag service action is entered in your Audi

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event w ithout the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehic le-related data
during norma l vehicle opera tion for diagnostic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehic le speed, direction,
braking as well as restraint system use and performance in the
even t of a crash or other condition . Stored data can only be read and
downloaded with special equipment.
Electronic Stabilization Program (ESP)
Genel'61
The Electronic Stability Program increases driving
sta bility.
Fig . 142 Cente r
cons ole with ESP
sw itch
With ESP, control over the veh icle is increased in situations when
the vehicle is close to the limits of grip, such as during acce leration
and in curves. ESP reduces the risk of skidding a nd improves vehicle
stability under all road conditions . It operates at all speeds .
The Anti-Lock Brake System (ABS), E lec tronic Differentia l Lock (EDS)
and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
H ow ESP work s
The ESP control unit processes the following data from high-sensi ­
tive sensors: the rotational speed of the vehicle about its vertica l
axis, fore -and -aft and lateral acceleration forces, brake pressure and
steering angle.
Using steering ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
actual vehicle behavior . If the two do not match, for example when

the vehicle begins to skid, ESP brakes the appropriate wheel auto­matical ly .
The vehicle is stabilized again by the forces acting on the wheel during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed .
This brake application is accompanied by noises.
ESP works in conjunction with ABS=:>
page 189. If there is ma lfunc­
tion in the ABS, ESP is also inoperative .
Activa ting
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode . With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 184, fig. 142 returns the
system to normal operation.
D eac tiva ting
ESP should norma lly be activated at all times because this ensures
optimum vehicle stability . Only in certain exceptional cases it does
make sense to deactivate Anti -Slip Regulation (ASR) or the Elec ­
tronic Stability Program !ESP) by pressing the button =:>
page 184,
fig. 142. Both deactivation stages can only be activated from normal
mode.
Dea cti vat ing ASR
Tap the switch . Deactivation is indicated by s low flashing of the ESP
lamp in the instrument c luster. In certain situations (e.g. driving
with snow chains, in deep snow or on loose ground, or when rocking the car free), it may be necessary to deactivate ASR. Deacti ­
vation is effective only up to a speed of about 45 mph (70 km/h). At higher speeds, ASR is switched on again automatical ly in front ­
whee l drive vehicles, deactivation is possible only up to about 30
mph (50 km/h). With a ll -whee l drive vehicles, ASR is active above
Controls and equip­
ment Safety first Vehicle operation
In
te llig ent tec hn olo gy
about 45 mph (70 km/h) and deactivated automatical ly below this
speed.
D eac tiva tin g ES P/ASR
Press the button for more than 3 seconds . Deactivation is indicated
by the ESP lamp in the instrument c luster staying on permanently .
This deactivates the E lectronic Stabi lity Program (ESP) in addition to
ASR . No Electronic Stability System operation and no Anti-Slip
Regu lation is availab le across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stab le vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traff ic situation permit .
& WARNING
• The limi ts of ph ysics ca nnot be suspe nd ed by E SP. E ven in vehi ­
cles w ith ESP, you should always adapt your dr iving to road and

Ii ] Tip s
In the event of a defect in the rear spoiler system or in Audi
magnetic ride, it can happen that ASR and ASR/ESP cannot be deac ­
tivated, or they are activated automatica lly in the deactivated
state. •

Electronic differential lock (EOL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDU helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or
almost no grip. Without EDL, this would be difficult, if not impos ­
sible.
How the system works
Th e EDL operates automatically. It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=> page 189. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power
to the other drive wheel or wheels (all-wheel drivel. This is done up
to a speed of about 60 mph (100 km/hl. Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate . If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected
to excessive loads, the EDL cuts out temporarily . The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning . This is
indicated by the ABS warning light=>
page 20. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates , the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface .
How the system works
ASR performs automatically, i.e. without the driver's intervention .
With the aid of the ABS sensors =>
page 189, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface . The system is active across the entire
speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action .
~

Faults in the brake syst em
If you shou ld notice a sudden i ncrease in brake pedal travel, then
one of the two brake circuits may have failed=>
& -
Low brake fluid level
Ma lfunctions can occur in the brake system if the brake fluid leve l is
t oo low. The brake fluid level is moni tored e lect ronica lly .
Brake pow er assist unit
The brake p ow er assist un it increas es th e pressure that you
generate with the brake peda l. It works only when the engine is
running.
& WARNING
• You should perform braking maneuver s for the purpose of
c leaning the brake system only if road conditions permit . Other
road users must not be put at ri sk -you may cause an accident!
• Before des cending a steep grade , redu ce speed and sh ift trans­
mi ssion into a lower gear or lower driving position . Do not ride the
br akes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency .
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature we ar and increased stopping distan ce .
• Under certain cl imatic and operating condit ions such as
pas sing through water , driv ing in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can ac cumulate on the brake pads , linings , discs and drums .
Cautiously apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few cautious brake appli cations .
• Driving for an extended period of time on salt -covered road s
without using your brakes can also affect brak ing effic iency . Clean
off accumulated salt coating from brake discs and pads with a few
c autiou s brake applications .

ARNING (continued )
• If you damage the front spo iler , or if you install a different
s poiler , be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat redu cing the effective­
ness of the entire br ake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increa sed stopping distance. Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop.
• Never let the veh icle roll to a stop with the engine shut off .
• If the b rake booster is not working , for e xample when towing
your vehicle, or because the brake booster has somehow been
damaged , the brake pedal must be pre ssed considerably harder to
make up for the lack of booster assistance . •
Anti- lock brake system (ABS)
ABS p revents the wheel s from loc king unde r br ak ing.
The anti -lock brake sys te m (ABS) makes a major contri but ion to

& WARNING
• ABS cannot suspend the la ws of physics . You should keep this
in mind in particular on an icy or wet road . If ABS control of braking
intervenes , you should adjust your speed immediately to road and
traffic condit ions. Do not be tempted by the increased safety
provided to t ake risks -danger of an accident.
• Please keep in mind that the risk of an accident is increased by
dri ving too fast, pa rticularly in bends and on icy or wet roads , and
by driving too close to the vehicle ahead . The increased risk of an

Fabrics and fabric coverings
Fabrics and fabric coverings (e .g. seats, door trim pane ls, etc.)
should be cleaned at regu lar intervals with a vacuum cleaner. This
removes surface dirt particles which could become embedded in
the fabric through use . Steam c leaners should not be used, because
the steam tends to push the dirt deeper into the fabric and lock it
there .
Norm al c leanin g
Generally, we recommend using a so ft sponge or a l int -free
microfiber cloth to the clean fabric. Brushes should only be used for carpets and floor mats, since other fabric surfaces could be harmed
b
y brushes .
Normal surface stains can be cleaned using a commercially avail­
able foam cleaner . Spread the foam on the surface of the fabric with
a soft sponge and work it in gently. Do not saturate the fabric. Then
pat the foam dry using absorbent, dry cloths (e.g. microfiber c loth)
and vacuum it af ter it has dried complete ly .
C leaning st ains
Stains caused by beverages (e.g . coffee, fruit juice, etc.) can be
treated with a mild detergent solution. Apply the detergent so lution
with a sponge . In the case of stubborn stains, a de tergent paste can
be applied directly to the stain and worked into the fabric. After ­
wa rds, use copious amounts of clean wa ter to remove the
remaining detergent . App ly the water with a damp cloth or sponge
and pat the fabric dry w ith an absorbent, dry c lo th.
Stains from choco late or makeup shou ld have detergent paste (e .g.
ox -gall soap) rubbed into them . Afterwards, remove the soap with
water (damp sponge).
Alcoho l can be used to treat stains from grease, oi l, lipstick or a ba ll­
point pen . Melted grease or dye must be patted off using absorbe nt
material. It may be necessary to retreat the areas with detergent
p aste and wa ter.
I n the case of general soiling of the upholstery and cover material,
we recommend hiring a specialist that has the equipment to clean
the seat covers and other fabr ic surfaces by shampooing and spray
extraction.

clothing materials can discolor leather seats (especially if such
clothing is damp and was not dyed correctly). Dust and dirt particles
in pores, folds, and seams can have an abrasive effect and can
damage the leather surface as well as weaken seams.
The leather should be cleaned regularly as needed. After having
been used for a relatively long time, your leather seats will acquire
a rich aged finish. This is a characteristic of natural leather and a
sign of true quality.
In order to maintain the value of this natural product over the life of
your vehicle, you should follow the recommendations below:
0 Note
• To keep your leather from bleaching out, do not allow it to be
exposed to bright sunlight for long periods of time. If you have to
leave the vehicle parked outside for long periods, cover the leather
to protect it from direct exposure to sunlight.
• Sharp objects on clothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or scrape marks on the
surface of the leather.
[ i J Tips
• After each time you clean the leather and at regular intervals, use
a leather preservative creme that contains UV -blockers and that
works into the leather. This creme will nourish and moisturize the leather, helping it to breathe and stay supple. It also helps to build
up a protective coating on the surface.
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc. as soon as possible.
• Preserve the color of the leather as needed by using a special
colored leather care creme to touch up areas of uneven color. •
Applies to vehicles: w ith natu ral leather
Cleaning and caring for leather upholstery
and trim
Natural leather requires special care and attention.
Normal cleaning
-Clean soiled areas with a slightly moistened cotton or
woolen cloth.
More stubborn dirt
- More stubborn dirt can be removed using a cloth satu­
rated with a mild soap solution (2 tablespoons mild
liquid soap).
- Never allow the soap solution to saturate the leather, and
make certain that no water soaks into the seams.
Wipe off the soap solution with a soft, dry cloth.
Cleaning spots
-Remove fresh water-based spots (such as coffee, tea,
juices, blood) with an absorbent cloth or paper towel.
- Remove fresh
grease or oil-based spots (such as butter,
mayonnaise, chocolate) with an absorbent cloth or paper
towel, or use the cleaner from the leather care kit if the
spot has not yet penetrated into the surface of the
leather.
- Use an oil/grease dissolving spray, if
oil/grease spots
have dried on.
- Remove specific kinds of spots (ballpoint pen, felt
marker, fingernail polish, water-based paint, shoe polish,
etc.) with a spot remover specifically formulated for leather. ..,_

Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig. 155 Engine
compartment: brake
fluid reservoir
Before you check anything in the engine compartment,
always read and heed all WARNINGS =>
& in "Working in
the engine compartment" on
page 220.
- Read the brake fluid level from the brake fluid reservoir
~ fig. 155. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located behind the rear partition of the
engine compartment on the left side~
page 221 .
The fluid level may drop slightly after some time due to the auto­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably below the "MIN" mark, the
brake warning/indicator light (U .S. models:
BRAKE , Canadian models:
ill) will come on~ page 20 and~ page 32. Do not continue to
operate the vehicle . The complete brake system should be thor­
oughly checked by an authorized Audi dealer or other qualified
facility and the cause corrected. If the brake fluid level is too low, the
brake warning/indicator light will illuminate. Contact an authorized
Audi dealer
immediately .•
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the air. If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The boiling point of the brake fluid will als o
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan ­
dard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we
